Background / History

Inheriting Wonder Pet Store

Mu You grew up in his family's pet store. Two years before discovering Fool, his parents died in a car accident and left the business to him. He quit his job and returned to his hometown to fulfill their wish of restoring the store, but the pandemic and declining brick-and-mortar trade made it difficult to survive 1 14.

A USB drive appeared inexplicably on the shop counter, containing Fool (Closed Beta Version 2.41) and an invitation code. After installing it, Mu You received the Time Pocket Watch in his actual hand. His employee could not see the watch, but he proved its effect by reversing a falling glass and catching it before it shattered 1 2.

Reviving the Business with Magic

After obtaining Animal Speech, Mu You trained his hamster Seventeen and uploaded an edited before-and-after video to Bilibili, excluding the magical footage. Overnight, the video surpassed 500,000 views and brought his follower count close to 100,000. He opened the store to a waiting crowd with eleven magically trained animals 5 6.

The shop earned more than 15,000 yuan on its first successful day, and Mu You rewarded Xiao Ya with 500 yuan. Rather than exploit his powers at casinos, he chose to keep the store as his legitimate income source and grow stronger without attracting other players' attention. As demand increased, he hired qualified veterinarian Lin Xue 13 14 33.

Peaceful Village and the Werewolf

In Peaceful Village, Mu You used information from Scarecrow to access the missing Night Watchman's estate. Inheriting its skin and house gave him a disguised identity, a respawn point, and a nightly patrol that could earn lifespan 9 11 12.

The village's Werewolf repeatedly killed his character. Unable to defeat it directly or escape its chained hook, Mu You exploited its habit of biting him: he poisoned himself so that eating him killed the Werewolf. The first victory raised him to level two; later poison kills forced the level-seven Werewolf, Deer Eater, to avoid him 17 18 36.

Mu You also mapped Peaceful Village's thirty-four buildings and forty-two residents. His investigation narrowed the Werewolf's possible daytime identity to five suspects: the little girl, drunkard, playboy, young carpenter, and village chief 36.

Evidence of real-world wolf attacks made the conflict more urgent. While investigating a crime scene at Rainbow Bay, Mu You encountered the wounded Werewolf on a rooftop and nearly died. A hidden player's flame attack gave him enough time to activate the watch and escape the encounter through a rewind 20 38 39.

That player wore a little girl's Wizard Apprentice skin and had stolen from the Werewolf's organization. Mu You later reversed her beheading and intervened with arrows, traps, and a fire spear. Police arrived during the confrontation, and Mu You subsequently possessed the Werewolf's Butcher's Bone-Cleaver 39 40 41 43.

Rescuing Cola

The Night Watchman's diary led Mu You to an otherworldly creature hiding in an abandoned lumber mill. He recognized its enormous monster form as an illusion, chased its actual American Shorthair body into a trap, and opened negotiations in Star Spirit Language 21 24 25.

The Familiar, later called Cola, refused to accept a second master. Mu You instead offered food, shelter, and help contacting its original master in exchange for assistance. Cola agreed to stay with him, and Mu You left the mill after asking Lin Hai to conceal his involvement 26 29.

The Dark Forest Trials

Seeking faster growth after witnessing the rooftop battle, Mu You traveled toward the Dark Forest to find the Witch. Along the way, he captured and contracted a Pocket Toad, took its Phoenix Feather, and released it to travel and bring back treasures 43 44 45.

Meeting the Witch of Calamity required joining the Mystic Arts Association. As candidate 13600, Mu You used rewinds to investigate the trials' lethal choices and recover their hidden instructions. He rejected a potion granting 1,000 strength after recognizing that it represented uncontrollable power; the alchemist confirmed that it would turn its user into a dim-witted baboon 47 48.

He passed the remaining trials by confronting transformation rather than accepting another monstrous form, choosing the Fool card to match his identity, and balancing a treasure scale by value rather than weight. After joining the association, he found Anthony Vivian's corpse in a forest cabin. Her spirit emerged from the guiding crow and named him her successor 49 50.

Appearance

• Normal form: Originally stands just under 1.8 meters tall, with an initially indistinct eight-pack 12.
• Night Watchman form: At least 1.95 meters tall, with a sturdier build, powerful limbs, sharply defined muscles, pale skin, and blood-red eyes 12.
• Skin clothing: Loose dark-red cloth garments and a dark scarf concealing the lower half of his face 12.
• Possible lingering skin effects: Develops dark circles, paler skin, and bloodshot eyes even outside the transformation. He suspects prolonged skin use changes a player's natural appearance, but has not confirmed the explanation 13 45.

Personality

Mu You is an experienced gamer who treats dangerous encounters as systems to investigate. He tests alternate choices, preserves information through rewinds, and looks for loopholes in rewards and costs. His first response to the wounded hunter is to attempt robbery; after being killed, he rewinds, heals the hunter, and obtains all three offered spells instead of one 4.

He is cautious about exposing his identity. He conceals magical footage, avoids conspicuous money-making schemes, uses skins and invisibility for investigations, and asks witnesses to keep him secret. His caution has limits: he accepts the risk of rescuing the Wizard Apprentice player, both to repay her earlier intervention and to prevent the Werewolf from eliminating a potential ally 5 14 26 41.

His persistence can become extreme. Opening the Witch's magically sealed house takes more than 100,000 rewind-assisted attempts and nearly causes a mental breakdown. After succeeding, he resolves not to repeat such exhausting work unless necessary 34.

Abilities & Skills

Time Reversal

Mu You's Time Pocket Watch reverses the preceding five seconds and has a five-second cooldown. His memories remain intact when the rest of the situation resets 1 2 4.

• Choice testing: Retries lethal encounters and compares alternate outcomes 2 17 31.
• Knowledge retention: Keeps learned incantations and purchased information after undoing the transaction 4 16.
• Random-result manipulation: Repeats roulette spins and low-probability unlocking attempts until obtaining the desired result 29 34.
• Resource restoration: Rewinds expended mana and physical injuries within the reset window 34 39.
• Limits: Must activate the watch in time; a restrained arm can prevent access. Repetition does not erase accumulated memories or mental strain, and retries alone cannot overcome every combat disadvantage 17 34 38 39.

Spellcasting

Mu You casts spells through learned incantations and a wand. Repeated use consumes mental energy; roughly a dozen consecutive early casts leave him dizzy, nauseous, and in need of rest 3 6.

• Animal Speech / Beast-Taming Spell: Grants animals enough intelligence to understand commands. Success becomes less likely with more advanced animals; repeated practice lets him silently recite the incantation in under half a second 4 6.
• Beast Trap: Consumes wood or metal to create a concealed trap. Used to catch Seventeen, Cola, the Werewolf, and the Pocket Toad 4 5 25 41 44.
• Sure Shot: Temporarily improves accuracy with ranged weapons. Mu You uses it to shoot away the Werewolf's Chain Claw during the rooftop rescue 4 41.
• Heartlock Unseal: Bypasses locks, including a phone lock screen. More difficult magical locks may have extremely low success rates; the Witch's door requires prolonged rewind-assisted attempts 30 34.
• Apparition: Built into his epic wand; teleports him and nearby people or objects to another location 49.

Night Watchman Skin

The complete Night Watchman skin changes Mu You's face, physique, and clothing, allowing him to operate under an inherited identity 12.

• Patrol income: Awards one year of lifespan for at least one hour of outdoor patrol between midnight and 4 a.m., once per day 11 12 18.
• Property inheritance: Grants ownership of the Night Watchman's Wooden House and control over its Magic Pumpkin Lock 12.
• Meditation: Spending one action point inside the house increases mental-power recovery tenfold, but prevents his character from acting during meditation 12.
• Not a dedicated combat skin: He remains substantially outmatched by the Werewolf and the powerful little girl early in his progression 17 31.

Enhanced Physique and Investigation

Leveling in Fool improves Mu You's actual body, including strength, movement, eyesight, and hearing 18 19.

• After reaching level two, his punches leave afterimages, and he can hear insects' wings beneath distant streetlights 18.
• Runs more than twenty kilometers home in about an hour and still has energy remaining 28.
• Uses the Pumpkin Lantern to follow hidden bloodstains, detect fabricated wounds, and reconstruct movement through crime scenes 16 30 38.
• Learns enough Star Spirit Language to communicate with Cola and uses a dictionary to translate the Night Watchman's diary 15 21 25.

Equipment / Weapons / Items

• Time Pocket Watch — Copper-cased watch with a white face, top button, and golden chain; his principal time-reversal relic 1.
• Mithril Bow — Silver longbow forged with thunder snake tendon. Drawing it automatically creates an energy arrow that inflicts paralysis and slows its target; detached arrows quickly disappear 21 22.
• Butcher's Bone-Cleaver — Rare-grade weapon taken from the Werewolf. Bypasses magical defenses, reduces movement and attack speed by 85% for five seconds, and causes persistent bleeding. Its weight imposes lengthy recovery between swings unless used with the Butcher Wolf skin, which Mu You has not acquired 43.
• Epic teleportation wand — Red-and-black hardwood wand with spiral carvings and a purple glow. Improves casting speed and range by 30%, resists disarming, and supplies Apparition 49.
• Pumpkin Lantern — Reveals details invisible to ordinary sight at night, including hidden trails and suspicious wounds 11 16 30.
• Night Watchman's Backpack — Shape-changing entrance to a pocket world containing a small wooden hut and a grassy field roughly the size of a soccer pitch. The game refuses to open it while it contains an Earth drinking glass 11.
• Invisibility Cloak — Conceals his appearance but not sounds or scent. Useful against surveillance and ordinary observers, but unreliable near a high-level player who can hear him breathing 3 36 38.
• Night Watchman's Notebook and Star Spirit Dictionary — The diary supplies clues to Cola; the dictionary enables translation 14 15 21.
• Bloodstained Police Badge — Hunter's reward capable of compelling a villager to perform a task 16.
• Phoenix Feather — Fiery-red feather with a golden flame pattern and faint warmth. Mu You carries it because its effect activates upon his death 45.
• Potion-brewing pot — Reward obtained during the association trials 49.
• Fool card — Surviving choice in the fortune-teller's trial; shows no obvious special effect when Mu You examines it 50.
• Aries Ring — Received upon completing the trials and joining the Mystic Arts Association 50.
• Capture and exploration supplies — Veterinary tranquilizers, throwing knives, climbing rope, binoculars, an entrenching tool, and stab-resistant clothing purchased for the lumber-mill expedition 22 25.

Relationships

• Shen Ya / Xiao Ya — Longtime pet store employee who has worked with him for over two years. Helps manage the shop's sudden popularity and notices changes in his behavior and appearance 1 6 14 38 45.
• Zhao Qian — Customer who offers access to her family's Era's Adorable Pets Breeding Center and recommends Lin Xue 13 33.
• Lin Xue — Veterinarian hired by Mu You. Examines the store's animals and recommends vaccinations and monthly checkups for Cola 33.
• Seventeen — Hamster used for his first practical Animal Speech and trap tests; becomes the subject of his viral training video 5 6.
• Cola — American Shorthair Familiar housed as a partner rather than a replacement master's pet. Supplies knowledge about the Star Spirit World, magical equipment, and the Witch of Calamity 26 43 47.
• Pocket Toad — Contracted Familiar that Mu You releases to travel and return with treasures 44 45.
• Long-Bearded Hunter — Rescued villager who rewards him with spells and later the Bloodstained Police Badge 4 16.
• Scarecrow — Lifespan-charging information broker. Mu You repeatedly retains its information through rewinds; it later refuses to speak to him, though his suspicion that it discovered the trick remains unconfirmed 9 16 29.
• Deer Eater / Werewolf player — Level-seven adversary whom Mu You counters with poison in-game. In reality, the Werewolf's strength and equipment remain a serious threat 36 38 43.
• Wizard Apprentice player — Powerful player appearing as a little girl through a skin; actual age and gender are unknown. Her attack saves Mu You in an erased timeline, and he later rewinds to save her from beheading 39 41.
• Lin Hai — Paranormal livestreamer who mistakes Mu You for a reclusive master and enthusiastically promises to conceal his involvement at the lumber mill 24 26.
• Anthony Vivian — Deceased Witch of Calamity whose surviving spirit recognizes Mu You as her successor and offers three possible legacies 50.
